A few months ago, a group of students in Oslo produced a brilliant spoof video that lampooned the charity pop song genre. It showed a group of young Africans coming together to raise money for those of us freezing in the north. “A lot of people aren’t aware of what’s going on there right now,” says the African equivalent of Bob Geldof. “People don’t ignore starving people, so why should we ignore cold people? Frostbite kills too. Africa: we need to make a difference.” The song – Africa for Norway – has been watched online two million times, making it one of Europe’s most popular political videos.

The aim was to send up the patronising, cliched way in which the West views Africa. Norway can afford to make the joke because there, people don’t tend to die of the cold. In Britain, we still do. Each year, an official estimate is made of the “excess winter mortality” – that is, the number of people dying of cold-related illnesses. Last winter was relatively mild, and still 24,000 perished. The indications are that this winter, which has dragged on so long and with such brutality, will claim 30,000 lives, making it one of the biggest killers in the country. And still, no one seems upset.

Somewhere between the release of the 1984 Band Aid single and Al Gore’s 2006 documentary An Inconvenient Truth, political attention shifted away from such problems. The idea of people (especially old people) dying in their homes from conditions with which we are all familiar now seems relatively boring. Much political attention is still focused on global warming, and while schemes to help Britain prepare for the cold are being cut, the overseas aid budget is being vastly expanded. Saving elderly British lives has somehow become the least fashionable cause in politics.

The reaction to the 2003 heatwave was extraordinary. It was blamed for 2,000 deaths, and taken as a warning that Britain was horribly unprepared for the coming era of snowless winters and barbecue summers. The government’s chief scientific officer, Sir David King, later declared that climate change was “more serious even than the threat of terrorism” in terms of the number of lives that could be lost. Such language is never used about the cold, which kills at least 10 times as many people every winter. Before long, every political party had signed up to the green agenda.

Since Sir David’s exhortations, some 250,000 Brits have died from the cold, and 10,000 from the heat. It is horribly clear that we have been focusing on the wrong enemy. Instead of making sure energy was affordable, ministers have been trying to make it more expensive, with carbon price floors and emissions trading schemes. Fuel prices have doubled over seven years, forcing millions to choose between heat and food – and government has found itself a major part of the problem.

This is slowly beginning to dawn on Ed Davey, the Secretary of State for Energy and Climate Change. He has tried to point the finger at energy companies, but his own department let the truth slip out in the small print of a report released on Wednesday. The average annual fuel bill is expected to have risen by £76 by 2020, it says. But take out Davey’s hidden taxes (carbon price floor, emissions trading scheme, etc) and we’d be paying an average £123 less. His department has been trying to make homes cheaper to heat, and in a saner world this would be his only remit: to secure not the greenest energy, but the most affordable energy.

By now, the Energy Secretary will also have realised another inconvenient truth – that, for Britain, global warming is likely to save far more lives then it threatens. Delve deep enough into the Government’s forecasts, and they speculate that global warming will lead to 6,000 fewer deaths a year, on average, by the end of the decade. This is the supposed threat facing us: children would be less likely to have snow to play in at Christmas, but more likely to have grandparents to visit over Easter. Not a bad trade-off. The greatest uncertainty is whether global warming, which has stalled since 1998, will arrive quickly enough to make a difference.

It’s daft to draw any conclusions from this freakish, frozen spring. But in general, the computer-generated predictions do not seem as reliable as they did when Al Gore was using them to scare the bejesus out of us. A few weeks ago, scientists at the University of Washington found that man’s contribution to global warming may have been exaggerated – by a factor of two. The natural cycle of heating and cooling, they discovered, plays a far bigger role than they had imagined. Mr Davey’s fuel bill taxes may do nothing for the planet. But they will certainly lead to poorer, colder homes and shorter lives.

Our understanding of climate science may be weak, but our understanding of basic medicine is not. Low temperatures increase blood pressure and weaken the immune system, making everyone more vulnerable to bugs. For the elderly, this can be fatal. People don’t actually die of frostbite, as the Norwegian video teasingly suggested. They die of flu, or thrombosis, or other conditions they would not have acquired if their house had been warmer. Far fewer Scandinavians die in winter, because they have worked out how to defeat the cold: keep the heating on; insulate houses. It really is that simple.

So what’s stopping us? For years, various government schemes have sought to insulate lofts or upgrade boilers, but nowhere near quickly enough. When MPs looked into this three years ago, they heard from a Mr P of Cornwall. “The offer of a boiler is very much appreciated,” he said. “We hope that we will still be alive when we get the visit about the end of February.” With someone dying of the cold every seven minutes during winter, that may not have been a joke. The modest insulation scheme has been hit by cuts, while the mammoth winter fuel payment scheme continues untouched. The word “fuel” is, of course, redundant: it’s a simple bung, paid to all pensioners – who are more likely to vote.

I once drank a winter fuel allowance. It had been paid to a self-made millionaire who was appalled that people like him were being written a cheque, and he had used it to buy a magnum of claret in protest. He was a major philanthropist, but wanted to make the point to his lunch guests: the winter fuel payment is a scandal, whose very existence suggests that government is not serious about helping people make it through winter.

No one would wear a wristband or pin on a ribbon for the elderly victims of the cold – and yet freezing weather kills more than diabetes or breast cancer. The cause of death is perhaps too familiar, and the remedy too obvious, to attract much attention. If the money for winter fuel payments was instead used to help insulate homes, we might – like Norway – be able to joke about winter. As things stand, dying of the cold remains a horribly British disease.
